Product description

Product Description

No matter how much experience you have with JavaScript, odds are you don’t fully understand the language. As part of the "You Don’t Know JS" series, this compact guide focuses on new features available in ECMAScript 6 (ES6), the latest version of the standard upon which JavaScript is built.

Like other books in this series, You Don’t Know JS: ES6 & Beyond dives into trickier parts of the language that many JavaScript programmers either avoid or know nothing about. Armed with this knowledge, you can achieve true JavaScript mastery.

With this book, you will:

  • Learn new ES6 syntax that eases the pain points of common programming idioms
  • Organize code with iterators, generators, modules, and classes
  • Express async flow control with Promises combined with generators
  • Use collections to work more efficiently with data in structured ways
  • Leverage new API helpers, including Array, Object, Math, Number, and String
  • Extend your program’s capabilities through meta programming
  • Preview features likely coming to JS beyond ES6

4.0 out of 5 stars Excellent coverage, but struggles with format, sometimes excessive examples. 31 July 2016

This book does a pretty great job at covering the new inclusions in ES2015 (aka ES6). While I hadn't read any of the previous entries in the series (I have subsequently), it wasn't difficult to follow. There were a few examples that could've been pared down but were instead approached from every angle. Some developers may appreciate this, some may not. I found myself skipping ahead in some parts after I felt I had a thorough understanding of the material.

I do wish the publishers/editors had made more of an effort to ensure code samples stopped and resumed on following pages in a better way. There were a number of times where a single variable would be declared at the end of one page, turn the page, and more declared on the following page. This made it (occasionally) difficult to remember what a variable was in the example.

Overall, this is a great overview of ES2015 and I'm sure will give experienced developers a quick read of the material.

5.0 out of 5 stars Crisp and Clear 23 February 2016

Probably the best of the series. Tightly written, yet still clear. And I was pleasantly surprised to find very little of Kyle's JavaScript idiosyncrasies present: he very clearly and honestly argued the pro's and con's of the "controversial" features like class and fat arrow. His recommendation to *only* use arrows when you want a lexical this—as opposed to when you want a lexical this, or don't need *any* this—was a bit odd, but it in no way detracted from the overall quality of the book.

Highly recommend.
